HAND AND POWER.

To all whom it may concern.-

Be it known that I, BENGT M. W. HANSON, a citizen of Sweden, but having declared my intention of becoming a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have inv ad certain new and useful Improve- Int' -5 in Hand and Power Controlled Gearingf \f which the following is a specification.

This invention relates to improved means whereby gearing of any sort may be driven either automatically or by hand and in which the act of disengagement of the manually-operative mechanism engages the driven parts with power mechanism, and when the power-driven mechanism is disengaged the manually-operated devices are thrown into operation. I

Primarily the object of the invention is the provision of either hand or power controlled devices and of clutchelements therein whereby when one clutch is thrown into action the other is disengaged, and vice versa. I p

A further object of the invention is the provision of details of improvement in mechanism of the class described, which will be hereinafter set forth.

In the accompan g drawing the view is a vertical sectiona VIGW of my improved mechanism, certain parts being in elevation, and the machine ,thus'illustrated disclosing one particular arrangement of the improvementswith certain driving and driven mechanism but it is distinctly to be understood may be variously modified as the conditions of construction may require.

Like numerals designate similar parts.

Referring to the drawing, the numeral 1 designates a part of a machine-frame of any suitable construction, and 2 a sleeve inserted in an o ening of the art 1 and provided with a auge 2, which may .be secured to said part by screws or otherwise. This sleeve isprovided at the right of the flange in the cbnstructionillustrated with an extension 2 counterbored at 2 to produce an enlarged circular'ehamber for a, purpose here inafter described, and it also is provided at its end with a rabbet 2 for a purposehereim ,1 Jaftersetforth- Specification of Letters Patent.

' pulled CONTROLLED GEARING- Patented July 10, 1906.,

Fitted in the sleeve is a tubular shaft 3, carrying a pinion 4 at its inner end, said shaft being slotted at 3. Mounted in the tubular shaft 3 is a rod 5, slotted or chambered at 5 to receive a clutch lever or dog 6, which is pivoted to the rod at 6 and has a heel 6 projecting from its pivot and a clutch extension or nose 6 At its inner end the rod 5 is connected by a pin 7 with a clutch 8, said pin working in slots 9 of the shaft. This tubular shaft 3 is threaded at its outer end at 10, and on the threaded portion is fitted a I nut 11, having a recess or chamber in its inner face to receive a washer 12, said washer being restrained from rotation on the shaft 3 by a key 13, which fits in a slot in its periphery, but being free for slight movement longitudinally on said shaft when it is actuated by the nut 11. tween the nut 11 and the extension 2 of sleeve 2 is the hub 14 of a wheel 15, having a handle 16, by which it may be manipulated, the inner end of said hub Ibeing inserted within the rabbet 2 of the extension 2 Normally the hub of the hand'wheel is loose on. the shaft 3, and it can be readily engaged and disengaged from said shaft in a manner now to be described.

At its outer projecting end the rod 5 is chambered at 18, and threaded into said chamber is the stem 19 of a knob 19. In said chamber 18 is a spring 20, which bears at one end against the extremity of the threaded stem 19 and at its other end against a pin 21, having an angular extension 21 in engagement with the heel of the clutch lever or dog 6 and serving normally to rock said dog upon its pivot and to throw its clutch end outward. In the hub of the hand-wheel 15 is formed a keyway 22 for the reception of the nose 6 of the clutch dog or lever 6. In the drawing the end of the clutch-lever is shown in engagement with the keyway of the hub and the parts are ariang'ed for the manual transmission of power, the rod 5 being out and the clutch b being released from the oomplemental clutch element with which it is adapted to engage. In a bearing 24 of another part of the frame 1 is mounted the hub25 of a gear or other element 26, said hub 25 being keyed at 27 to a shaft 28, and

. said shaft terminating atits inner end in an Mounted on the shaft beenlarged flanged head having a clutch surface 30. At its extreme outer end the shaft 28 is threaded to receive a spanner nut the bearing 24.

,31, and said nut and the flange of the head 'retain the hub and its gear or other ele ment 26 against longitudinal movement in In mesh with the pinion 4 on the inner end of shaft'3 is a large spur-gear 32, and rigid In the operation of the invention when theparts are in the position represented in the drawing the hand-Wheel is clutched to the shaft 3 and. the clutch 8 is disen aged from the complemented clutch on s liaft 28, so that by turning said hand-Wheel the gear 32 will be driven. and the pinion 33 Will actuate fanydesired henhowever, the rod f5is, pushed inward, the end of the clutch-dog 6 leaves the spline in the hub of the hand- Wheel and enters themircular groove, or chamber 2 in the end of the sleeve 2. This action throws the clutch 8 ii to engagement With the clutch 30 on the head 19 of the shaft 28, and as the gear 26 is actuated in any suitable manner (not shown) it will be seen that the said gear Will drivethe shaft 28 and through the connections described the tubular shaft 3, thus starting. into operation the gear 32 and pinion 33 and operating the part of the machine tobe driven. As will be obvious, when the, face of the clutch-dog 6 enters the chamber 2 in the extension of the sleeve 2 said doiwill rotate freely with the shaft 3.

i Washer 3-1 separates the pinion t from the end of sleeve 2, and said washer is slotted at 34 to receive a pin 35 of the shalt 3 Frequently it is necessary in automatic machines to stop the power-driven mechanism and to actuate certain parts by hand, and this may be readily accomplished by the con struction shown.

Changes may be made in the various details of the mechanism, the invention not being limited to the precise devices illustrated and described, and this mechanism may be employed With various machines and in various arts without departure from the invention.

Having thus described my invention, What I claim is' 1. The combination, with a shaft, of a han l wheel, sleeved thereon; a clutch for connecting said hand-Wheel with the shaft, and for disconnecting it therefrom; a pmver-driven element; a second clutch for connecting the shaft and said power-driven clement and means for simultaneously actuating the clutches, to throw one in and the other out of action.
